The company was founded on Sept. 19, 1952 in Santa Fe Springs, Calif., by John Morrisroe.
Morrisroe began the company with his patent for a process called ice-cold sulfonation, which resulted in higher quality products.
From Santa Fe Springs, the company first expanded to Lockland, Ohio, in 1963; then Avenel, N.J., in 1968; Houston in 1973; and Middletown, Ohio, in 1985.
The headquarters remained in Santa Fe Springs until a 2005 relocation to Cincinnati.
Currently, Pilot has 285 employees and sells worldwide.
The company acquired Mason Chemical Company (Arlington Heights, Ill.) in 2012; Liquid Minerals Group, Inc. (New Waverly, Texas) in 2016; and ATRP Solutions, Inc. (Pittsburgh) earlier this year.
“It is fitting to remember John Morrisroe on Pilot’s 65th anniversary,” said Mike Scott, Pilot Chemical’s president. “We owe much of the company’s success to the example he set.”
The company will officially celebrate the anniversary with a luncheon at its Cincinnati headquarters on Sept. 28.
